Description

  The present invention relates to the communication field, and more particularly, to an information configuration method, an information configuration apparatus, and a communication system.

  Multiple Input Multiple Output (MIMO) is one of the important physical layer technologies in LTE-Advanced systems, used to provide spatial diversity gain, spatial multiplexing gain, and array gain. It is done.

  In LTE Release 11 and previous technologies, all MIMO technologies employ a one-dimensional (1D) linear array arranged horizontally and are adaptive in the horizontal plane, ie two-dimensional (2D) MIMO technology. . 1 and 2 are diagrams showing the structures of two types of conventional planar arrays. FIG. 1 is a structural diagram of a cross polarization two-dimensional planar array, and FIG. 2 is a structural diagram of a uniform linear two-dimensional planar array.

  In the research of Release 12, a 2D planar array has been introduced, using a technology related to Active Antenna System (AAS), and providing adaptive control in the horizontal and elevation dimensions. The performance can be improved better, ie 3D MIMO technology.

  As shown in FIG. 1, M cross-polarized antenna pairs (pairs) are arranged in each column on the vertical direction, and a total of N cross-polarized antenna pairs (pairs) are arranged on the horizontal direction. . As shown in FIG. 2, M array antennas with the same polarization direction (for example, the vertically polarized antenna in FIG. 2) are arranged in each column on the vertical direction, and a total of N columns are arranged on the horizontal direction. Is done. In these two types of configurations, the number of antenna ports in the horizontal direction may be the same as the number of antenna ports in the previous LTE release, such as 1, 2, 4, 8, etc. A plurality of physical antennas in the vertical direction virtualize one physical antenna port, thereby reducing the number of antenna ports that transmit reference signals. When the number of antenna ports in the vertical direction is 1, the 2D planar array is reduced to the conventional 1D array, and the 3D MIMO technology is correspondingly reduced to the 2D MIMO technology.

  The introduction of the background art described above is intended to clearly and completely explain the technical solution of the present invention so that those skilled in the art can easily understand it. These schemes are described in part of the background of the present invention and should not be construed as well known to those skilled in the art.

  When the number of antenna ports in the vertical direction is larger than 1, the 3D MIMO technology can be fully utilized to adjust the transmitted signal on the horizontal and vertical planes, but the total number of antenna ports is the number of ports in the previous release Therefore, the number of resources occupied by the reference signal, in particular, the channel state information reference signal (CSI-RS, Channel State Information Reference Signal) increases. In addition, since the antenna is changed from one dimension to two dimensions, the reference signal configuration information in the previous release may cause confusion under the two-dimensional plane array. For example, when only the total number of antenna ports is configured, since there are a plurality of antenna arrangement methods that can satisfy the number of antenna ports, the number of antenna ports in the horizontal and vertical directions cannot be obtained accurately on the receiving side.

For example, according to the protocol TS 36.331 of the current release, V11.5.0 can be used to configure the horizontal direction and the There is no need to separate the vertical direction. That is,
antennaPortsCount-r10 ENUMERATED {an1, an2, an4, an8},
resourceConfig-r10 INTEGER (0..31),
subframeConfig-r10 INTEGER (0..154),
pC-r10 INTEGER (-8..15)
It is.

  However, when the previous release antennas are all one-dimensional and the number of antenna ports is indicated by the configuration information, the current antenna arrangement scheme can be determined. When a two-dimensional antenna array is used, the antenna arrangement method cannot be determined by notifying only the number of antenna ports. FIG. 3 is a diagram showing a possible antenna arrangement in the case of 8 antenna ports, and FIG. 4 is a diagram showing a possible antenna arrangement in the case of 4 antenna ports. As shown in Figures 3 and 4, 8 antennas and 4 antennas show 7 and 5 possible antenna configurations respectively, so it is not enough to configure the number of transmit antenna ports according to the current release protocol only It is.

  The foregoing and other features of the present invention will become apparent upon reference to the accompanying drawings and the following description.

It should be noted that the present invention is not limited to the described implementations, i.e. includes all modifications, variations and alternatives within the scope of the appended claims. Hereinafter, various embodiments of the present invention will be described with reference to the drawings. In addition, these implementation systems are only illustrations and are not for limiting the present invention.

  Embodiment 1 of the present invention provides an information configuration method. FIG. 5 is a flowchart of the method, and as shown in FIG. 5, the method includes the following steps.

Step 501: The base station performs virtualization on the two-dimensional planar antenna array (also called after two-dimensional planar antenna array virtualization) (ie, two-dimensional planar antenna). Mapping relationship between configuration information of one or more sets of reference signals and instruction information for indicating configuration information for user equipment (based on antenna ports formed by virtualizing the array) Comprising:
The configuration information inclusion includes antenna polarization indication information, horizontal or vertical antenna port indication information; number of horizontal antenna ports and number of vertical antenna ports; total number of antenna ports in the system and horizontal antenna ports. Number; total number of antenna ports in system and number of antenna ports in vertical direction; antenna arrangement method instruction information; instruction information on whether to weight reference signals; number of configured reference signals; user-specific vertical reference Number of signal ports; number of columns where antenna ports are located in vertical direction; number of antenna ports in each column in vertical direction or total number of antenna ports occupied in vertical direction; number of ports of horizontal reference signal dedicated to users; horizontal direction The number of the row where the antenna port is located in the horizontal direction; and the number of antenna ports in each horizontal row or the horizontal Tenapoto including total, one or more of.

  In this embodiment, the base station configures the configuration information for the user equipment based on the antenna port formed after performing virtualization on the two-dimensional planar antenna array. It can be made suitable for a two-dimensional planar antenna array, so that the user side can accurately obtain array configuration information.

  In this embodiment, configuration information can be indicated using an n-bit indication state, where n is a positive integer. For example, 1-bit indication states “0” and “1” may be used to indicate 2 sets of configuration information; 2-bit indication states “00, 01, 10, 11” are used to set 4 sets. The configuration information may be indicated. Note that how many bits are used to instruct the configuration information may be determined according to the actual situation.

  In this embodiment, the base station side configures the above-described mapping relation, and stores the mapping relation on the user side and the base station side, so that the user apparatus can respond to the instruction information after receiving the instruction information. Corresponding processing can be performed based on the configuration information. Hereinafter, how to configure the above configuration information and the above mapping relationship on the base station side will be exemplarily described.

  In one implementation of the present embodiment, when the configuration is performed separately for the horizontal or vertical antenna port, the configuration information includes the horizontal or vertical antenna port indication, the antenna polarization indication, and / or the antenna. Includes sequence instructions.

  In this case, since the user side can determine the array configuration on the transmission side based on the configuration information described above, it is not necessary to separately configure the total number of antenna ports of the system. Therefore, the user side can recover the information of the entire channel (the channel constituted by all the antennas on the transmission side and the antennas on the user side), thereby reducing the occupied resource elements and improving the data transmission service. Therefore, it is possible to avoid a decrease in the number of resource elements and improve the system throughput.

  Among them, the configuration information may further include horizontal and / or vertical resources, and / or subframes, and / or power information.

In this embodiment, when the configuration is performed independently for the horizontal or vertical antenna port, the configuration information may include the following specific information:
(1-a) Horizontal or vertical antenna port indications enumeration {horizontal, vertical},
(1-b) Polarization indication Enumeration {0/90 cross polarization, 45 / -45 cross polarization, vertical polarization, horizontal polarization,…},
(1-c) Number of antenna ports enumeration {an1, an2, an4, an8},
(1-d) resourceConfig-r10 INTEGER (0..31),
(1-e) subframeConfig-r10 INTEGER (0..154),
(1-f) pC-r10 INTEGER (-8..15)
It is.

  In the present embodiment, the configuration may be performed only in the horizontal direction, the configuration may be performed only in the vertical direction, or the configuration may be performed in each of the horizontal direction and the vertical direction.

  In the present embodiment, the configuration information including the above-described information is one set or a plurality of sets, and may be indicated by n-bit instruction information. Note that the number of bits to be specifically adopted may be determined according to an actual situation.

  For example, when configuring in the horizontal direction and configuring four sets of configuration information, as shown in Table 1, it may be indicated by employing 2-bit instruction information. Since the configuration in the vertical direction is similar to that in Table 1, detailed description thereof is omitted here.

Table 1 shows the mapping relationship between configuration information and instruction information.

  In another implementation method of the present embodiment, when a configuration is performed for a horizontal or vertical antenna port with a joint, the configuration information includes an antenna polarization instruction and / or a horizontal and vertical antenna port. Includes numbers. Among them, the configuration information may further include horizontal and vertical resources, and / or subframes, and / or power information.

  In the present embodiment, the resource information and / or subframe information in the horizontal direction and the vertical direction may be configured as one set or one or more sets. For example, among the following configuration information examples, (3-c) Is an example in which the resource information is configured as one set, and (4-c) is an example in which the resource information is configured as one or more sets.

For example, when performing a configuration with a joint for a horizontal or vertical antenna port, the configuration information includes the following specific information:
(2-a) Polarization instructions Enumeration {Cross polarization, vertical polarization, horizontal polarization,…},
(2-b) Number of horizontal antenna ports Enumeration {an1, an2, an4, an8, ...},
(2-c) Number of vertical antenna ports Enumeration {an1, an2, an4, an8, ...},
(2-d) Horizontal direction resourceConfig-r10 INTEGER (0..31),
(2-e) Vertical direction resourceConfig-r10 INTEGER (0..31),
(2-f) Horizontal subframeConfig-r10 INTEGER (0..154),
(2-g) Vertical subframeConfig-r10 INTEGER (0..154),
(2-h) Horizontal pC-r10 INTEGER (-8..15),
(2-i) Vertical direction pC-r10 INTEGER (-8..15)
It is.

  In the present embodiment, when the parameters in the vertical direction and the horizontal direction are always the same, it may be configured only once.For example, (2-f) and (2-g) are combined, and (2 -h) and (2-i) are merged.

  In other implementations of the present embodiment, when performing a configuration for a horizontal or vertical antenna port with a joint, the configuration information includes an antenna polarization indication and / or the total number of antenna ports in the system, and Includes the number of antenna ports in the horizontal or vertical direction.

For example, the configuration information (2-b) and (2-c) described above may be changed as follows:
(2-b1) Total number of antenna ports in system Enumeration {an1, an2, an4, an8, ...},
(2-c1) Horizontal antenna port number enumeration {an1, an2, an4, an8, ...}, or
(2-b2) Total number of antenna ports in system enumeration {an1, an2, an4, an8, ...},
(2-c2) Number of vertical antenna ports Enumeration {an1, an2, an4, an8, ...}
It is.

  Similarly, the configuration information including the above-described information is one set or a plurality of sets, and may be indicated by n-bit indication information. Note that the number of bits to be specifically adopted may be determined according to an actual situation. Since this is similar to Table 1 described above, a detailed description thereof is omitted here.

  In another implementation method of this embodiment, when a configuration is performed for an antenna port that does not distinguish between the horizontal direction and the vertical direction, the configuration information includes the number of antenna ports and antenna arrangement method instruction information.

For example, when performing configuration for an antenna port that does not distinguish between the horizontal direction and the vertical direction, the configuration information includes the following specific information:
(3-a) Number of antenna ports Enumeration {an1, an2, an4, an6, an8, an9, an10, an12, an15, an16, ...},
(3-b) Antenna arrangement method instructions Enumeration {a, b, c, d, e, f, g, h, i, ...},
(3-c) resourceConfig-r10 INTEGER (0..31),
(3-d) subframeConfig-r10 INTEGER (0..154),
(3-e) pC-r10 INTEGER (-8..15)
It is.

  Among them, a, b, c, d, e, f, g, h, i, etc. in (3-b) are numbers of possible antenna arrangement methods.

  Similarly, the configuration information including the above-described information is one set or a plurality of sets, and may be indicated by n-bit indication information. Note that the number of bits to be specifically adopted may be determined according to an actual situation. Since this is similar to Table 1 described above, a detailed description thereof is omitted here.

  In the present embodiment, when estimation and feedback are performed independently in the horizontal direction and the vertical direction, the change characteristics of each channel are different, and therefore, the configuration period and / or the feedback period of the two may be different. is there. Therefore, relatively accurate channel estimation results can be obtained using such characteristics. Hereinafter, the case where the configuration / feedback cycle in the vertical direction is longer than that in the horizontal direction will be described as an example.

であり、xは、W_Vの列数及びW_Hの行数を示し、例えば、x＝NN_V(N_V＜M)であり、N_Vは、垂直方向にサポートするデータ流の数である。この場合、3Dチャネルと垂直及び水平方向のプリコーディング行列の乗積は、次のようなブロック行列とすることができる。

The format of the signal received on the user side is Y = HW _V W _H s + n, of which H is the channel that is actually transmitted, and W _V and W _H are vertical and horizontal precoding matrices, respectively. S and n are the transmitted signal and the noise placed on the user side, respectively. The dimensions of the channel and precoding matrix are
(Outside 1)

Where x indicates the number of columns of W _{V and} the number of rows of W _H , for example, x = NN _V (N _V <M), and N _V is the number of data streams supported in the vertical direction. . In this case, the product of the 3D channel and the vertical and horizontal precoding matrices can be a block matrix as follows.

Among them, H _n = (n = 1, 2,..., N) is a channel message between the physical antenna in the nth column on the transmission side and all antennas on the user side, and W ⁿ _V (M × N _r ) is a precoding matrix of the n-th vertical channel, and N and M are the number of antennas in the horizontal and vertical directions, and are positive integers. Thus, a vertical precoding matrix W ⁿ _V (M × N _r ) or a plurality of W ⁿ _V (M × N _r ) or W _V using one column of H or a part of all or all columns. It is better to obtain a lot of channel information in order to estimate the whole matrix and to estimate the PMI in the vertical direction.

  In the present embodiment, x may take a value by adopting another method, and the present embodiment is not limited to this.

  Since the position where the user edge is located is different, the difference between the channels in each column in the vertical direction is also different. When the difference between the channels in each column is relatively small, the estimated PMI value for each column is the same. In order to use the resources of the reference signal most effectively, different configurations are performed on the user side, so that different numbers of vertical channels (antenna ports arranged vertically in each column and user side) A channel formed by all antennas may be one vertical channel). At the same time, the column number where the vertical antenna is located may be transmitted so that the user side can better restore the entire 3D channel information.

  Therefore, in the present embodiment, the configuration information may be further configured to include one or more of the following information, that is, instruction information for weighting the reference signal; Number of reference signals in the vertical direction dedicated to the user; number of columns in which the antenna ports are located in the vertical direction; number of antenna ports in each column in the vertical direction or total number of antenna ports occupied in the vertical direction The number of ports in the horizontal reference signal dedicated to the user; the number of the row where the antenna port is located in the horizontal direction; and the number of antenna ports in each row in the horizontal direction or the total number of antenna ports occupied in the horizontal direction.

In one implementation of this embodiment, the configuration information includes the number of configured reference signals. For example, when configuring a plurality of reference signal resources for a vertical antenna, the configuration information is May include:
(4-a) Number of antenna ports in each column in the vertical direction Enumeration {an1, an2, an3, an4,…},
(4-b) Number of columns where antenna ports are located in the vertical direction Enumeration {c1, c2, c3, ...},
(4-c) resourceConfig-r10 INTEGER (0..31), INTEGER (0..31), INTEGER (0..31), ...
(4-d) subframeConfig-r10 INTEGER (0..154),
(4-e) pC-r10 INTEGER (-8..15)
It is.

Among them, etc. c1, c2, c3, a combination of different number of plurality of rows, for example, when the four columns of antenna systems exist, a combination of possible row has two ^four, i.e., the 4-bit Can be used to represent all 16 possible combinations. In addition, the bit mapping method may indicate the occupation status of the columns of the vertical antennas, that is, the antennas of the four columns, each antenna of each column is represented by 1 bit, and the value of the corresponding bit is 1. Being present indicates that a reference signal resource is configured for the vertical column, and a corresponding bit value of 0 indicates that no reference signal resource is configured for the column.

  Similarly, the configuration information including the above-described information is one set or a plurality of sets, and each may be indicated by n-bit instruction information. Note that the number of bits to be specifically adopted can be determined according to an actual situation. Since this is similar to Table 1 described above, a detailed description thereof is omitted here.

  In this embodiment, by configuring multiple sets of configuration information, that is, by indicating the use of multiple reference signal resources, the receiving side estimates more channel information for better CSI measurement. can do.

In one implementation of this embodiment, the configuration information includes the number of configured reference signals. For example, when configuring one reference signal resource for all antennas occupied in the vertical direction, The configuration information may include the following:
Total number of antenna ports occupied in the vertical direction Enumeration {an1, an2, an3, an4,…},
Number of columns where antenna ports are located in the vertical direction Enumeration {c1, c2, c3,…},
resourceConfig-r10 INTEGER (0..31),
subframeConfig-r10 INTEGER (0..154),
pC-r10 INTEGER (-8..15)
It is.

  In this case, an antenna port that transmits reference signals in a plurality of columns in the vertical direction occupies a single reference signal configuration having a large number of ports.

In this embodiment, after the user end obtains W _V or a precoding matrix W ⁿ _V (M × N _r ) of some columns, the vertical PMI update period is relatively long, so that HW _V or HW _The horizontal PMI can be estimated using some columns of _V. Like the vertical direction but also the horizontal direction of the reference signal, it is possible to estimate the entire row of HW _V to occupy relatively large resources, also part of the HW _V only to save part of the resources Since the configuration method is the same as the vertical configuration method, detailed description thereof is omitted here.

However, at the time of the horizontal reference signal at this time, it is necessary to perform weighting using all or a part of the sub-matrix blocks of W _V , and in this embodiment, in order to distinguish from the reference signal in the vertical direction, The configuration information may further include instruction information for weighting the reference signal, for example,
Weighting instructions enumeration {Yes, No}
It is.

  In this embodiment, when the horizontal configuration / feedback period is longer than the vertical direction, the vertical reference signal may also include instruction information on whether to weight the reference signal. Since the configuration / feedback cycle is similar to the implementation method in the case of being longer than the horizontal direction, detailed description thereof is omitted here.

  In the present embodiment, the above-described reference signal may be CSI-RS or an antenna reference signal with a channel estimation function in the communication system, and is not limited to this in the present embodiment.

  In the present embodiment, the above configuration method may be used alone or in combination with information included in the configuration message. For example, when the number of antenna ports in the system is relatively large (greater than at least 8), for example, a uniform linear two-dimensional planar array as shown in FIG. It is also possible to define any one or a plurality of rows of antennas as horizontal antenna ports, and configure the antenna ports independently in the horizontal and vertical directions. Or you may comprise by a joint with respect to the port of a horizontal direction and a perpendicular direction. In addition, for example, when the number of antenna ports of the system is not large, for example, when the number of antenna ports is 8 or less or 16 or less, the configuration method that does not distinguish between the horizontal direction and the vertical direction is used in addition to the configuration method described above. You may do it. In addition, what is demonstrated here is only an illustration and is not limited to this in the Example of this invention.

  As can be seen from the above embodiments, the base station configures the configuration information for the user equipment based on the antenna port formed after virtualization of the two-dimensional planar antenna array, so that the configuration information is two-dimensional. It can be made suitable for a planar antenna array, whereby the array configuration information can be obtained accurately on the user side.

  The second embodiment of the present invention further provides an information configuration apparatus as described in the second embodiment, and the principle by which the information configuration apparatus solves the problem is similar to the method of the first embodiment. For the implementation, reference can be made to the implementation of the method in Example 1, and a duplicate description with the same content is omitted.

FIG. 6 is a configuration diagram of an information configuration apparatus in Embodiment 2 of the present invention. As shown in FIG. 6, the apparatus 600 includes:
